The name's Josh Wahlie. I drive a 2000 F-250 and I work for a local stereo shop called wicked kustomz. I am the sales manager, but I compete in competitions. My current setup is 4 15" Boss Audio 1400 watt Subs on a Hifonics xx-Colossuss ii in SS 3-4. I'm hitting 147.0. We are starting up our own brand of subs and I will be taking this wall out for a Street C setup with 2 real 15's.
